Protein attributes
| Sequence length | 869 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Chloride transport protein, initially identified as voltage-gated chloride channel. The presence of the conserved gating glutamate residues suggests that is functions as antiporter. |
| Subcellular location | Endosome membrane; Multi-pass membrane protein. Note: Detected in detergent-resistant lipid rafts. Ref.11 |
| Tissue specificity | Testis, ovary, small intestine, brain and skeletal muscle. Low level expression in aortic and coronary vascular smooth muscle cells, and aortic endothelial cells. Isoform C is only detected in kidney. Ref.1 Ref.2 Ref.10 |
| Post-translational modification | N-glycosylated on several asparagine residues. Ref.11 |
| Miscellaneous | The CLC channel family contains both chloride channels and proton-coupled anion transporters that exchange chloride or another anion for protons. The presence of conserved gating glutamate residues is typical for family members that function as antiporters By similarity. |
| Sequence similarities | Belongs to the chloride channel (TC 2.A.49) family. ClC-6/CLCN6 subfamily. [View classification] Contains 2 CBS domains. |
